Reddit mentions of The Languages of Native North America (Cambridge Language Surveys)

The best book, by far, is The Languages of Native North America by Marianne Mithun .

It is dense, but a book of this scope needs to be. Nevertheless I do think it is accessible to the interested layperson.

The Languages of Native North America is still the classic introduction to North American languages. Although more work has been done, the basics haven't changed.

Of course, you'll need something more specific for a paper topic - just listing information isn't a good approach to a paper. Also, it's not particularly productive to look for sources until you've come up with something more specific. There are a lot of sources on Native American languages out there, and what's useful to you will depend on your topic.

Not sure if this is what you're looking for, but Marianne Mithun's The Languages of Native North America is perhaps a good place to start and definitely an amazing source of information.

I am printing the hell out of this to put on my wall.

For people that are interested in Native linguistics, I would definitely recommend acquiring: Mithun's The Languages of Native North America

Pirahã is fairly analytic. While there are a good amount of suffixes that mark modality and aspect, there are no agreement patterns and those suffixes (I think) only have distribution in VPs. See The Handbook of Amazonian Languages vol. 1, 1986 for details. In addition, Mithun 1999's The Languages of Native North America reports that many of the Inuit trade pigeons were/are analytic.
